IMPROVEMENT IN SASH-FASTENERS.

Specification forming part of Letters Patent No. 1 74,501, dated March7, 18 76 application filed February 2, 1876.

Be it known that I, LLOYD J. EARLL, of

Pittsburg, in the county of Allegheny and State of Pennsylvania, have.invented a new and Improved Combined Sash Lock and Holder; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accom' panyingdrawing, forming apart of this specification, in .which Figure 1 is aview of one side of the device, showing its application to awindow-casing and the socket contained therein Fig. 2, a view of theopposite side of the device. Fig. 3 are different views of amodification of the socket. Fig. 4 is a side view of the catch.

My invention relates to certain improvements in that class of sash-lockswhich have an arc-shaped head or binding-surface, which bears eitheragainst the window-sash or is pivoted to the window-sash and bindsagainst the window-frame, for the purpose of holdingthe window-sash inany desired position.

My invention consists in the combination,

with a continuous band of rubber passing around the quadrant-shapedholder, of a post or stud attached to said holder, around which therubber band may be passed, to tighten the same whenever it becomes loosefrom Wear. I

The invention also consists in the combination of a sliding bolt passingthrough alug on said holder so as to enter a socket of the window-frame,and having a shoulder upon one side, so that when the bolt is in thesocket, and turned, it cannotbe withdrawn. The invention also furtherconsists in the particular form of a solid and chambered socket made toreceive the bolt, the same being made in and operating with a frictionalcontact therewith to hold the sash at any desired bright. The holder Ais made of metal or other suitable material; and, to prevent abrasionand scratching'of the paint, due to the friction of its curved face withthe painted wood-work, I provide it with a continuous flexible band, B,of leather, rubber, leather saturated with a solution ofrubber, or otherequivalentmaterial. Said band extends entirely around the outside edgesand curved face of the holder, and acts as a cushion to preventdisfiguring the paint. The band is made continuous, so that when oneportion becomes worn it may be turned soas to present a new face toengage the frame-work. To prevent the slipping of the band, and tocompensate for its looseness resulting from wear, I construct the holderwith a recess, 01, and a post or .stud, 6, around which post theloosened bandmay be passed to tighten it. (3 is a lug cast upon one sideof the holder, and having a hole through the same, in which slides thebolt D. Said bolt slides into or out from the socket in thewindow-frame, to lock or unlock the sash. This bolt D is made with oneside straight and smooth from end to end, but the other side is providednear its end with a locking-shoulder, j, which, when the bolt isprojected into the socket, and turned, binds against the edge gof thelug and prevents the withdrawal of the bolt until turned again. Thewindow-sash is by this means doubly locked, and a much greater securityaii'orded against the efforts of burglars. E is a socket, which receivesand holds the bolt when the sash is locked. It consists of a wedgeshaped piece of metal, which is provided with a hollow head and a flatface, and is driven into the wood-work until the face is flush with theguideway for the sash, in which position it is held without otherfastening. Instead of using this wedgeshaped socket, however, otherforms may be used, if desirable, such as are shown in Fig. 3 of thedrawing. I may also use my sash-holding devices separately from thelocking devices, as shown in Fig. 2.

Having thus described my invention, what I claim as new is- 1. Theholder A, having recess (1 and post FFIC'E e.in combination with,continuous flexible band ing a wedge-shaped end, adapted to be driven B,as and for the purpose described. 7 into the wook-work and held inplace, for the 2.
